Conti Synchroflex T10 1300

Conti Synchroflex T10 1300 – durable PU timing belt for standardized timing belt drives

This T10 timing belt is specified with a pitch length of 1300 mm and 130 teeth. The ratio between length and number of teeth is fixed: 1300 mm divided by 10 mm gives exactly 130 teeth. The Conti Synchroflex T10 1300 is supplied as a cast, endless PU belt, so there is no weld joint in the finished ring. The design is developed for synchronous operation and precise machine movements. This is the standard version in the specified profile. It should not be confused with a possible GEN III version or a double-sided DL belt with the same pitch length.

Fixed specifications

• Pitch length: 1300 mm

The list gathers the information normally used to identify a timing belt: nominal length, number of teeth, profile, material and make. It is important to read all the information together. Two belts can have the same pitch length but be incompatible if the tooth profile or tooth pitch is different. Conversely, a different width does not change the number of teeth as long as the profile and pitch length are the same.

Profile, tooth pitch and engagement

As a classic metric profile, the T-series is used in many machines where reliable synchronous movement is important. The tooth shape is trapezoidal, and the number in the profile designation indicates the tooth pitch in millimeters. The correct washer must therefore both have the same pitch and be manufactured for the T-profile. The wrong profile can lead to poor engagement, noise and rapid wear.

How the Conti Synchroflex belt is constructed

The endless PU construction combines low dead weight with high longitudinal rigidity. The steel cord tension elements are cast into the belt and are not intended to be exposed, damaged or sharply broken during installation. The wear resistance of the polyurethane and the strong bond to the cord are central to the belt's lifespan. Correct handling is therefore just as important as the correct choice of profile and length.

The specific product version

The product is the regular Conti Synchroflex standard version in the specified profile. Standard and GEN III may have the same pitch length and number of teeth, but they are different product series with different material construction and capacity data. The same applies to a DL belt, which has teeth on both sides. When reordering, the entire profile designation should therefore be checked, not just the length.

Typical applications and sizing

The profile series is used in practice for tasks such as machine tools, main and auxiliary drives, textile machines and printing machines. Common to these machines is the need for a fixed transmission ratio and controlled tooth engagement. A timing belt can transmit both force and position, but the capacity cannot be assessed based on length alone. Width, profile version, wrap angle and load cycle are among the data that must be included in the selection.

How the width variants work

This product line has been created with 6 mm as the base width because this is the width of the selected item and thus the SKU used for inventory control. Integer widths from 6 to 50 mm can be selected on this product page. The widths that appear as standard widths in the supplier data are marked separately in the options. The price surcharge is calculated as a percentage of the base width: doubling the width results in a surcharge of 100%. The technically necessary width should be selected according to the load and not only according to the price.

Disc geometry and tooth engagement

The pulleys and belt should be considered as a single tooth engagement. Correct T10 geometry ensures that the load is distributed over the tooth flanks instead of being concentrated on tooth tips or edges. The drive ratio is selected by the number of teeth on the pulleys, while the belt's 130 teeth and 1300 mm pitch length determine the required combination of pulleys and center distance. When changing the drive, the geometry should be calculated.

Pre-tensioning and disc alignment

The belt must be able to be placed on the pulleys without force. If it can only be mounted by forcing it over a flange, the center distance or mounting procedure is incorrect. The pulley shafts must be aligned and the flanges must be smooth and undamaged. In the case of multi-shaft or counter-bent drives, the diameter and position of the rollers must be assessed separately. Correct pretensioning reduces the risk of tooth skipping without unnecessarily loading the bearings.

Before ordering a replacement

When replacing a spare part, the marking on the existing belt should be compared with the product name. Check the profile designation, pitch length, number of teeth, design and width. If the text on the belt has worn away, the number of teeth can be counted and the pitch can be assessed by measuring over several teeth. A single external length measurement is less reliable because the nominal length of the timing belt is indicated in the pitch line.

Wear patterns and troubleshooting

Troubleshooting should start with pu location of the damage. Edge wear is typically associated with grooveing and alignment, while tooth skipping can be associated with too low tension, load peaks or too few teeth in mesh. Ctiming bars on the back can be caused by too small rollers, back bending or environmental influences. Do not simply replace the belt without also finding the mechanical cause.

Operating environment and maintenance

The standard material is specified for ambient temperatures from -30 °C to +80 °C. Applications close to the limits, especially below -10 °C or above +50 °C, may require special sizing. The molded PU belt is maintenance-friendly and does not require lubricant. Regular visual inspection is still relevant: look for ctiming bars, frayed edges, shiny tooth flanks, foreign body impressions and abnormal side contact. Sudden changes in noise or grooveing may indicate misalignment, too low tension or worn pulleys.

Frequently Asked Questions

How many teeth does the Conti Synchroflex T10 1300 have?

The belt has 130 teeth. The number of teeth is calculated by dividing the pitch length of 1300 mm by the tooth pitch of 10 mm. The result is 130, and this number can be used as an additional check when identifying an existing belt. A different number of teeth means a different pitch length.

Conti Synchroflex T10 1300: can this belt be used at high rpm?

The Conti Synchroflex series is designed for precise and fast synchronous drives, but the permissible speed depends on the profile, pulley diameter, belt width, load and peripheral speed. A high speed must therefore not be approved based on the product name alone; the drive must be calculated.

Conti Synchroflex T10 1300: what does the pitch length of 1300 mm mean?

The pitch length is the nominal length measured in the belt cord line where the steel cord tension elements are located. It is not the same as a random outer circumference measurement. For this belt, 1300 mm pitch length corresponds to 130 teeth with 10 mm tooth pitch.

Conti Synchroflex T10 1300: how does preload affect operation?

Correct pretension keeps the teeth in stable engagement and reduces the risk of tooth jump. Too low a tension can cause impact and jump under load, while too high a tension increases the load on the cord, pulleys and bearings. The correct value must be determined based on the drive's dimensioning.

Conti Synchroflex T10 1300: why is 6 mm chosen as the basic width?

6 mm is the width of the supplier item whose SKU is used as the main product's stock reference. Other widths are handled as choices under the same product because they are cut from the same type of timing belt sleeve. The base width also determines the percentage-based pricing in the webshop.

Conti Synchroflex T10 1300: what is the difference between T10 and a GEN III belt?

This product is the standard version. GEN III is a separate reinforced series with red high-performance PU and denser, two-filament steel cord. The same profile and length therefore do not mean that the products are identical.

Conti Synchroflex T10 1300: what is the difference between tooth pitch and pitch length?

The tooth pitch is the distance from one tooth to the next and is 10 mm for this profile. The pitch length is the entire nominal circumference in the cord line and is 1300 mm. When the pitch length is divided by the tooth pitch, the belt has 130 teeth.

Conti Synchroflex T10 1300: is the polyurethane oil and chemical resistant?

The standard PU is described as resistant to simple oils, grease and petrol as well as certain acids and bases. This does not mean universal chemical resistance. In the case of continuous contact, high concentrations or cleaning agents, the specific liquid, temperature and exposure time should be assessed.

The most important thing about this size

The product brings together the specified T10 profile and length on one side, so that the appropriate width can be selected without creating a separate item for each cut. The main technical data is 1300 mm pitch length and 130 teeth. If in doubt about load or pulley compatibility, the drive should be calculated before ordering the belt.
